Pouzolzia zeylanica (L.) Benn., a perennial herbaceous medicinal plant from the Urticaceae family, is commonly found along roadsides throughout Bangladesh and is widely distributed across both Asia and Australia. This plant is traditionally used to treat a variety of ailments, including diarrhea, indigestion, infantile malnutrition, urinary difficulties, and injuries from falls. The aim of the current study was to analyze the phytochemical constituents and assess the in vitro antioxidant activity of the methanol extract of Pouzolzia zeylanica leaves. The antioxidant activity was evaluated using the 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) free radical scavenging method. The extract was found to contain various phytochemicals, including carbohydrates, tannins and phenolic compounds, saponins, alkaloids, flavonoids, gums and mucilages. In the DPPH assay, the leaves extract exhibited notable antioxidant activity, with an IC₅₀ value of 296.10±0.83 μg/mL, compared to ascorbic acid, which had an IC₅₀ of 5.25±0.27 μg/mL. In conclusion, the findings suggest that the methanol extract of Pouzolzia zeylanica leaves exhibit free radical scavenging potential, indicating its use as a natural antioxidant.
